OUR HISTORY

At age 35, Hank Gruy founded H.J. Gruy and Associates, Inc. During his tenure as chairman of Gruy, he was active in professional associations at the international, national, and state levels.

He was awarded the DeGolyer Distinguished Service Medal by the Society of Petroleum Engineers and the Lifetime Achievement Award from the Independent Petroleum Association of America. Among Hank’s industry achievements was serving as president of the Society of Petroleum Engineers (SPE) and serving as president of the Society of Petroleum Evaluation Engineers (SPEE). Hank was also recognized for Outstanding Achievements in the Field of Engineering by the Texas Society of Professional Engineers. He is a member of the National Academy of Engineering.

Hank earned a bachelor’s degree in petroleum engineering in 1937. After graduation from Texas A&M, Hank joined Standard Oil and Shell Oil Company. From 1945-1950, Hank worked for DeGolyer and MacNaughton as a petroleum engineer and geologist. Hank is currently Chairman Emeritus.

In 1996, the Gruy board of directors elected Marilyn Wilson as president of H.J. Gruy and Associates, Inc. Marilyn graduated from Texas A&M with a bachelor’s degree in petroleum engineering. She joined Gruy in 1982 following employment with a large pipeline company and a mid-sized independent E&P company.

Marilyn served 6 years on the national board of the Society of Petroleum Evaluation Engineers, culminating in her election as president of the Society in 2002—the first woman to serve in that capacity. During her tenure on the board of SPEE, she was an active founding member of the SPEE/SEC Steering Committee from 2000-2003. This committee created the SPE/SEC joint forum attended by industry leaders from all categories of public and private E&P producers, and the engineering staff of the United States Securities and Exchange Commission (SEC). This forum created the gateway for the current dialogue between the public energy companies and the SEC regarding reserves reporting compliance and SEC definitions.

Prior to her very active role with SPEE, Marilyn was chairman of the board of directors of the Gulf Coast Section of SPE (1996-1997), chairman of the Houston Chapter of SPEE (1997-1998), and chairman of the Reservoir Study Group of SPEE (1990-1991). She also served on the board of the Women’s Energy Network from 1999-2001.

Marilyn is currently the chairman and president of H.J. Gruy and Associates, Inc. and has devoted her career to the advancement of professionalism in reservoir engineering.
